How to Store / Freeze This Casserole
Allow the yellow squash casserole to cool completely before storing. This helps to prevent condensation, which can make the dish soggy.
Transfer the casserole to an airtight container or cover the baking dish tightly with plastic wrap or aluminum foil. This ensures that the casserole stays fresh and prevents it from absorbing other odors in the fridge.
Store the casserole in the refrigerator for up to 3-4 days. For best results, reheat in the oven at 350°F (175°C) until warmed through, about 15-20 minutes.
For freezing, portion the casserole into individual servings. This makes it easier to thaw and reheat only what you need.
Wrap each portion tightly with plastic wrap, then place in a freezer-safe bag or container. Label with the date to keep track of freshness.
Freeze the yellow squash casserole for up to 2-3 months. To reheat, thaw in the refrigerator overnight, then bake at 350°F (175°C) until heated through, about 20-25 minutes.
For a quicker reheating option, use the microwave. Place the thawed portion in a microwave-safe dish, cover, and heat on medium power in 1-minute intervals until hot.
How to Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the leftover yellow squash casserole in an oven-safe dish. Cover it with aluminum foil to prevent it from drying out. Bake for about 20-25 minutes, or until heated through. This method helps maintain the casserole's crispy topping and creamy interior.
Microwave Method: Transfer a portion of the casserole to a microwave-safe dish. Cover it with a microwave-safe lid or a damp paper towel to retain moisture. Heat on medium power for 2-3 minutes, stirring halfway through to ensure even heating. Be cautious not to overheat, as this can make the squash mushy.
Stovetop Method: Place the leftover casserole in a non-stick skillet over medium-low heat. Add a splash of milk or broth to keep it moist. Cover and heat for about 5-7 minutes, stirring occasionally, until warmed through. This method is great for small portions and helps retain the dish's texture.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the casserole in an air fryer-safe dish. Heat for 5-7 minutes, checking halfway through to ensure it doesn't overcook. This method can help restore some of the original crispiness to the topping.
